browser-or-node

What is browser-or-node?

The 'browser-or-node' npm package is a utility that helps developers determine whether their code is running in a browser or Node.js environment. This can be particularly useful for writing isomorphic JavaScript that needs to behave differently depending on the runtime environment.

What are browser-or-node's main functionalities?

Detect if running in a browser

This feature allows you to check if the code is being executed in a browser environment. The 'isBrowser' boolean will be true if the code is running in a browser.

const { isBrowser } = require('browser-or-node');

if (isBrowser) {
  console.log('Running in a browser');
}

Detect if running in Node.js

This feature allows you to check if the code is being executed in a Node.js environment. The 'isNode' boolean will be true if the code is running in Node.js.

const { isNode } = require('browser-or-node');

if (isNode) {
  console.log('Running in Node.js');
}

Detect if running in a web worker

This feature allows you to check if the code is being executed in a Web Worker environment. The 'isWebWorker' boolean will be true if the code is running in a Web Worker.

const { isWebWorker } = require('browser-or-node');

if (isWebWorker) {
  console.log('Running in a Web Worker');
}
